First up, Suicide Squad - or, The First Time Harley Quinn Gets In A Movie.
...I'm not sure. A lot of the internet seems pretty pleased with it, but... well, I'll need to see more of Harley and more of Leto's Joker. I'm getting the impression that Harley's origin has been totally retconned for this. I dunno. We'll see.
Also, Batman Vs. Superman: Dawn of Justice.
If this doesn't end with Batman beating the shit out of Superman, I will be disappointed.
